扫描仪输入字符串无空格？

Question

I was wondering how I can do this.

I was told to use kb.nextLine() instead of kb.next() , but that just results in the input being skipped when I run the program.

String address;
student.setAddress(address = kb.nextLine()); 

I was then told to do this to fix it:

student.SetAddress(String address = kb.nextLine());

but I get an error: String cannot be resolved into a variable" "Syntax error on token "address"

Your second example is wrong. Your first example looks okay. But not great. I assume you've been using something like nextInt() or nextDouble() . They leave a trailing new line, so you need to consume it.

kb.nextLine(); // <-- consume empty trailing line.
String address; 
student.setAddress(address = kb.nextLine()); //<-- reads line.

If you don't need a local copy of address,

kb.nextLine(); // <-- consume empty trailing line.
student.setAddress(kb.nextLine()); //<-- reads line.

As Scanner.nextLine() Javadoc says,

Advances this scanner past the current line and returns the input that was skipped.
